CABLEWAY-GABRIER.

Specification of Letters latent.

Patented Uct. 2a, rare.

Application filed February 23, 1916. Serial No. 79,830.

To all whom it may concern:

Be it known that 1, J H H. VVILsON, a citizen of the United States,residing at San Mateo, in the county of San Mateo, State of California,have invented a new and useful Cableway-Carrier, of which the followingis a specification in such full and clear terms as will enable thoseskilled; in the art to construct and use the same. i

This invention relates to a carrier for cable ways capable of operatinga load and to, traverse the cable way by operating from a singlehoisting cable, means being provided for releasing and for engaging thehoisting hook upon its arrival at either end of the cable Way.

It will be understood that while the term cable way has been used hereinthat it is also possible to provide a rigid elevated track for thesupport of this apparatus, the operation in that case beingsubstantially the same as with a cable, except that for present purposesa special carriage is used when a rigid track is employed.

An embodiment of the invention is shown in the drawing in which the samereference numeral is applied to the same portion throughout, but I amaware that there may be many modifications thereof.

Figure 1 is a side elevation of the complete apparatus, the cable waybeing shown horizontally instead of inclined for convenience ofillustration, Fig. 2 is a vertical sectional view of the carrier on theline 2-2, Fig. 1 looking in the direction of the arrows adjacent saidline, Fig. 3 is :1 vertical sectional view of the carriage, thesupporting hook being shown in edge elevation looking in the directionof the'arrows on the line 3443, Fig. 1. Fig. 4 is a side elevation ofthe complete apparatus as used in conjunction with a rigid track, saidtrack also being shown level instead of inclined for convenience ofillustration, and Fig. 5 is a view in elevation of the apparatus shownin Fig. 4 looking in the direction of the arrows on the line 5-5, Fig;4.

It will be understood by those skilled in the art that this carrier isintended to be used in conjunction with an inclined cable way where theinclination is sufliciently great to cause the carrier supporting thebucket or fork to travel away from the winding drum.

The numerals 1 and 2 indicate suitable posts from which a cable? issuspended,

said cable affording a track for the carrier.

The carrier comprises two duplicate rectan gular frames consisting of atop piece 4, bot-, tom piece 5 and three connecting vertical bars 6, 7,and 8. The two frames are suitably bolted 'together and are held a givendistance apart by means of the spacers 8.", 9 and 10 which surround thebolts connecting the two frames together. At the upper corners of theframes there are two pulleys 11 and 12 which ride on the cable 3 andthereby support the carrier. At one lower corner ofthe frame which inpractice is the upper lower corner there is a pulley 13 for the hoistingcable 14.

The two bars 5 have two depending plates 16: and 16 connected therewith,which plates have a V notch in their lower edges and a deep slot todirect the course of the hoisting block into position in front of thehook bar 17 At the front the plates 16 and 16 have two downwardlyextending bars 18 and 19 which carrya' small roller 20 for control: lingthe direction of the cable 14. The cable 14 has one end secured to a pin21 and it passes through a guide ring 22 under the pulley 23 of a block24. This block has a guide ring 25 surrounding the two parts of thecable at the upper portion of the pulley and it has a hook 26 forconnecting the block with the bail 27 of a suitable scoop 28 or otherhoisting apparatus. At the upper end of the block 24 there is a bar 29which is adapted to engage a bar 30 pivoted to the lower bars of theframe at 31. After en gaging the bar 30 the rod 29 comes in contact withthe hook on the lower end of the bar 17 and will remain connectedtherewith since the bar 30 lifts another bar 32 which has a pin 33extending between the two bars 6 and"? for the purpose of disengagingthe hook 34 from the pin 35.

Suspended on the cable at the end away fronr the hoisting apparatus is ablock 36, said block having suitable bolts 37 to connect it with thecable and it is provided with the bar 34 which is normally held downagainst the set screw 38 by means of a spring 39. The set screw 38 iscarried by a bracket 40 and is used for the purpose of adjusting theposition of the bar 34 so that it will always remain properly engagedwith the pin 35 when the carriage strikes the block. The bar 17 has arod 41 pivotally connected therewith and it extends between two pins 4%and 4 he length 9 hsi' 41 i e 1 adjusted that when the carrier strikesthe bumper 36 the hook 17 will be released from the fall block andpermit the descent of the bucket, but as soon as the bucket starts thedescent of the hook 34 will hold the carriage from shifting itsposition. The bar 17 is held normally in the position shown in Fig. 1by. means of a stiff spring 44 and at its upper end the hook has a bar45 connected therewith which extends forwardly to a lever 46 pivoted toa forwardly extending bracket 47 connected with the bar 8. The lever 46has a pin 49 and the bracket 47 has a pin 50. On the cable at thehoisting end is a block 51 which has a pivoted hook 52 carried therebyand which hook is held normadly in the position shown in Fig. 1 by meansof a stiff spring 53. A hand cable 54 is used to release the hook 53when necessary. The cable 14 passes over a pulley 55 on the post at thehoist.

In operation the carriage will ride down hill to the block 36 and whenthe rod 41 strikes said block the hook 17 will release the pin 29 andallow the bucket to descend to be loaded. At the same time the hook 34will engage the pin 35 and will hold the carriage in position for thebucket to be loaded, while as soon as the bucket is loaded and ishoisted the pin 29 will contact with the bar 30 and thereby disengagethe hook 34 from the pin 35 thereby allowing the carriage to begin totravel toward the hoist, but at the same time the hook 17 has beenengaged with the pin 29 and the bucket will remain suspended beingpulled along by the cable 14. If it is not desired to bring the bucketup to the mast 1 it may be dumped at any convenient position by the useof suitable apparatus, a self-dumping bucket such as is shown in myco-pending application Ser. No. 78,100 filed Feb. 14, 1916, being'usedfor this purpose, but if it is desired to lower the bucket beforedumping the carriage is drawn up until the pin 49 engages the stop block51, whereupon the hook 17 will release the bucket and at the same timethe carriage will move back far enough to permit the hook 52 to engagethe pin thereby holding the carriage at the upper end of the cable waywhile the bucket is being loaded for dumping. WVhen the bucket has beendumped it will be again hoisted and the spring 44 is made sufficientlyheavy to prevent the pin 49 from causing the hook to be disengaged whenthe bucket is hoisted so that as soon as it is again connected with thecarriage the hook 52 may be released by pulling the hand cable 54,whereupon the carriage will be ready to move down on the cable way foranother trip.

I In order to make the apparatus adaptable for use. with rigid rails thecarriage shown in Figs. 4 and 5 is used. In these figures the numeral 60represents a rigid rail pivotally supported by suitable legs (51, onlythe upper portions of which are shown in Fig. 4, at one end and bysimilar legs or a cable 62 at the other end. This rail has angle irontracks 63 and 04 on its upper corners and it is capable of turning withrespect to the cross bar 61 on the pin 61. The track supports a carriageformed with two inverted U shaped members (35, 66. These two inverted Ushaped members are connected by means of four bars 67, (38, 69 and 70which bars hold them in the position shown in Fig. 4. At the upper endof the U shaped members there are four wheels 71, 72, 73 and 74 whichride on the angle bars on the upper edge of the rail. The U shapedmembers are bolted together by means of bolts 75, 76-=and they have twodepending rings 77, 78 which rings are connected with the hoistingcarriage shown in the preceding figures by removing the wheels 11 and 12and passing the bolts through the rings instead of the wheels. The block36 is then suspended from the track by means of two eyebolts 80, 81, arod 81 taking the place of the cable and the block 51 is suspended fromthe opposite end of the track by means of two eyebolts 82, 83, a rod 82taking the place of. the cable at that end of the track.

The operation of the apparatus is substantially identical with theoperation of the preceding apparatus when used in connection with thecable way, except that the rails upon which the auxiliary carriage ismounted are rigid and the tripping blocks are suspended lower than withthe other form of cable way.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States, is as follows, expressreservation being made of permissible modifications: 1. A travelingcarrier hoist comprising a frame, wheels at the upper portion thereoffor the support of the frame, a hook carried by the frame, a fall blockadapted to be supported by said book, a cable extending to the frame andaround the fall block, spring operated bumpers to release the book fromthe fall block whenever the carrier moves to either end of its way,means to hold the carriage at one end of the way, and means operated bythe fall block to release the carriage while supporting the fall blockwhereby the carriage may be returned to the opposite end of the way.

2. A traveling carrier hoist comprising a rectangular frame, wheels atthe upper portion of the frame for the support of the for connecting thefall block to the frame, means to hold the carriage at one end of itspath of travel, means to release said carriage when the fall block is tobe engaged with the carriage, and a spring operated bumper to releasethe fall block from the carriage when it arrives at the opposite end ofits path of travel.

3. In a traveling carrier hoist, a rectangular frame, wheels at theupper portion of the frame for the support of the carrier, a pivotedhook, a fall block adapted to be supported by said hook, dependingplates to guide the fall block into said hook, means to hold saidcarrier at one end of its way, means operated by the fall block torelease the carriage to permit it to travel at the opposite end of itsway, and spring operated bumpers to cooperate with means at both ends ofthe way to release the fall block from the carriage and to hold it in agiven position until the load has been dumped.

In testimony whereof I have hereunto set my hand this 14th day ofFebruary A. D. 1916.

JOHN H. WILSON.
